[0266] Amino add: In its broadest sense, as used herein, the term "amino acid” refers to a compound and / or substance that can be, is, or has been incorporated into a polypeptide chain, e.g., through formation of one or more peptide bonds. In some embodiments, an amino acid has the general structure H2N-C(H)(R)-C00H. In some embodiments, an amino add is a naturally-occurring amino acid. In some embodiments, an amino acid is a nonnatural amino acid; in some embodiments, an amino add is a D-amlno add; In some embodiments, an amino acid Is an L-amlno add. "Standard amino acid* refers to any of the twenty standard L-amino acids commonly found in naturally occurring peptides. "Nonstandard amino add* refers to any amino add, other than the standard amino acids, regardless of whether it is prepared synthetical or obtained from a natural source. In some embodiments, an amino acid, including a carboxy- and / or amino-terminal amino add in a polypeptide, can contain a structural modification as compared with the general structure above. For example, in some embodiments, an amino add may be modified by methylation, amidation, acetylation, pegylation, glycosylation, phosphorylation, and / or substitution (e.g., of the amino group, the carboxylic add group, one or more protons, and / or the hydroxyl group) as compared with the general structure. In some embodiments, such modification may, for example, alter the circidating half-life of a polypeptide containing the modified amino acid as compared with one containing an otherwise identical unmodified amino add. In some embodiments, such modification does not significantly alter a relevant activity of a polypeptide containing the modified amino add, as compared with one containing an otherwise Identical unmodified amino add. As will be dear from context, in some embodiments, the term "amino acid' may be used to refer to a free amino add; in some embodiments it may be used to refer to an amino add residue of a polypeptide.

[0269] Assodated. Two events or entities are "associated" with one another, as that term is used herein, if the presence, level, degree, type and / or form of one is correlated with that of the other. For example, a particular entity (e.g., polypeptide, genetic signature, metabolite, microbe, etc.) is considered to be assodated with a particular disease, disorder, or condition, if its presence, level and / or form correlates with incidence of, susceptibility to, severity of, stage of, etc. the disease, disorder, or condition (e.g., across a relevant population). In some embodiments, two or more entities are physically "assodated” with one another if they interact, directly or indirectly, so that they are and / or remain in physical proximity with one another. In some embodiments, two or more entities that are physically associated with one another are covalently linked to one another; in some embodiments, two or more entities that are physically associated with one another are not covalently linked to one another but are non- covalently associated, for example by means of hydrogen bonds, van der Waals interaction, hydrophobic interactions, magnetism, and combinations thereof.

[0270] Characteristic portion. As used herein, the term "characteristic portion', In the broadest sense, refers to a portion of a polypeptide or region thereof whose presence (or absence) correlates with presence (orabsence) of a particular feature, attribute, or activity of the polypeptide or region thereof. In some embodiments, a characteristic portion of a polypeptide or region thereof is a portion that is found in the polypeptide or region thereof and in related polypeptide or region thereof that share the particular feature, attribute or activity, but not in those that do not share the particular feature, attribute or activity. In certain embodiments, a characteristic portion shares at least one functional characteristic with the intact polypeptide or region thereof. For example, in some embodiments, a "characteristic portion" of a polypeptide or region thereof is one that contains a continuous stretch of amino acids, or a collection of continuous stretches of amino acids, that together are characteristic of the polypeptide or region thereof. In some embodiments, each such continuous stretch generally contains at least 2, 5, 10, 15, 20, 50, or more amino acids. In general, a characteristic portion of a polypeptide or region thereof is one that, In addtion to the sequence and / or structural Identity specified above, shares at least one functional characteristic with the relevant intact polypeptide or region thereof. In some embodiments, a characteristic portion may be biologically active. In some embodiments, a fragment as described herein can be a portion. Accordingly, in some embodiments, a characteristic fragment can be a "characteristic portion."

[0271] Combination therapy. As used herein, the term "combination therapy" refers to those situations in which a subject is simultaneously exposed to two or more therapeutic regimens (e.g., two or more therapeutic agents (e.g., two or more antibody agents)). In some embodiments, the two or more regimens may be administered simultaneously; in some embodiments, such regimens may be administered sequentially (e.g., all "doses" of a first regimen are administered prior to administration of any doses of a second regimen); In some embodiments, such agents are administered in overlapping dosing regimens. In some embodiments, administration of combination therapy may involve administration of one or more agent(s) or modality(ies) to a subject receiving the other agent(s) or modallty(les) in the combination. For clarity, combination therapy does not require that Individual agents be administered together In a single composition (or even necessarily at the same time), although In some embodiments, two or more agents, or active moieties thereof, may be administered together In a combination composition.

[0272] Comparable; As used herein, the term "comparable" refers to two or more agents, entitles, situations, sets of conditions, etc., that may not be Identical to one another but that are sufficiently slmiar to permit comparison there between so that one skilled In the art will appreciate that conclusions may reasonably be drawn based on differences or similarities observed. In some embodiments, comparable sets of conditions, circumstances, individuals, or populations are characterized by a plurality of substantially identical features and one or a small number of varied features. Those of ordinary skill in the art will understand, in context, what degree of identity is required in any given circumstance for two or more such agents, entities, situations, sets of conditions, etc. to be considered comparable. For example, those of ordinary skill in the art will appreciate that sets of circumstances, individuals, or populations are comparable to one another when characterized by a sufficient number and type of substantially identical features to warrant a reasonable conclusion that differences in results obtained or phenomena observed under or with different sets of circumstances, individuals, or populations are caused by or indicative of the variation in those features that are varied.

[0273] Corresponding toe As used herein, the term "corresponding to" refers to a relationship between two or more entities. For example, the term "corresponding to' may be used to designate the position / identity of a structural element in a compound or composition relative to another compound or composition (e.g., to an appropriate reference compound or composition). For example, in some embodiments, a monomeric residue in apdymer (e.g., an amino add residue in a polypeptide or a nucleic acid residue in a polynucleotide) may be identified as "corresponding to" a residue in an appropriate reference polymer. For example, those of ordinary skill will appreciate that, for purposes of simplicity, residues in a polypeptide are often designated using a canonical numbering system based on a reference related polypeptide, so that an amino add "corresponding to” a residue at position 190, for example, need not actually be the 190thamino add in a particular amino add chain but rather corresponds to the residue found at 190 in the reference polypeptide; those of ordinary skill in the art readily appreciate how to identify "corresponding" amino acids. For example, those skilled in the art wil be aware of various sequence alignment strategies, including software programs such as, for example, BLAST, CS-BLAST, CUSASW++, DIAMOND, FASTA, GGSEARCH / GLSEARCH, Genoogle, HMMER, HHpred / HHsearch, IDF, Infernal, KLAST, USEARCH, parasai, PSI-BLAST, PSI-Search, ScalaBLAST, Sequilab, SAM, SSEARCH, SWAPHI, SWAPHI-LS, SWIMM, or SWIPE that can be utilized, for example, to identify "corresponding" residues In polypeptides and / or nudeic acids in accordance with the present disdosure. Those of skill in the art wil also appreciate that, in some instances, the term "corresponding to” may be used to describe an event or entity that shares a relevant similarity with another event or entity (e.g., an appropriate reference event or entity). To give but one example, a gene or protein in one organism may be described as "corresponding to” a gene or protein from another organism in order to indicate, in some embodiments, that it plays an analogous role or performs an analogous function and / or that it shows a particular degree of sequence Identity or homology, or shares a particular characteristic sequence element

[0274] Dosing regimen-. Those skilled in the art will appredate that the term "dosing regimen” (or "therapeutic regimen”) may be used to refer to a set of unit doses (typically more than one) that are administered Individually to a subject, typically separated by periods of time. In some embodiments, a given therapeutic agent has a recommended dosing regimen, which may involve one or more doses.

[0275] Encodes, ks used herein, the term "encode" or "encoding" refers to sequence information of a first molecule that guides production of a second molecule having a defined sequence of nucleotides (e.g., a polyribonucleotide) or a defined sequence of amino adds. For example, a DMA molecule can encode an RNA molecule (e.g., by a transcription process that Indudes a DNA-dependent RNA polymerase enzyme). An RNA molecule can encode a polypeptide (e.g., by a translation process). Thus, a gene, a cDNA, or an RNA molecule encodes a polypeptide if transcription and translation of RNA corresponding to that gene produces the polypeptide In a cell or other biological system. In some embodiments, a coding region of a polyribonudeotide encoding a target antigen refers to a coding strand, the nudeotide sequence of which is identical to the polyribonucleotide sequence of such a target antigen. In some embodiments, a coding region of a polyribonudeotide encoding a target antigen refers to a non-coding strand of such a target antigen, which may be used as a template for transcription of a gene or cDNA.

[0276] Expression-. As used herein, the term "expression" of a nucleic acid sequence refers to the generation of a gene product from the nudeic add sequence. In some embodiments, a gene product can be a transcript, e.g., a polyribonucleotide as provided herein. In some embodiments, a gene product can be a polypeptide. In some embodiments, expression of a nudeic add sequence involves one or more of the following: (1) production of an RNA template from a DNA sequence (e.g., by transcription); (2) processing of an RNA transcript (e.g., by splidng, editing, etc.); (3) translation of an RNA into a polypeptide or protein; and / or (4) post-translational modification of a polypeptide or protein.

[0277] Heterologous: As used herein, the term "heterologous", with respect to secretory signal or transmembrane region, refers to a secretory signal or transmembrane region from a virus or an organism other than Piasmocfium.

[0278] Homology*. As used herein, the term "homology” or "homolog" refers to the overafl relatedness between polynucleotide molecules (e.g., DNA molecules and / or RNA molecules) and / or between polypeptide molecules. In some embedments, polynucleotide molecules (e.g., DNA molecules and / or RNA mdecides) and / or polypeptide molecules are considered to be "homologous" to one another if their sequences are at least 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, or 99% identical. In some embodiments, polynucleotide molecules (e.g., DNA molecules and / or RNA molecules) and / or polypeptide molecules are considered to be "homologous" to one another if their sequences are at least 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, or 99% similar (e.g., containing residues with related chemical properties at corresponding positions). For example, as is well known by those of ordinary skill in the art, certain amino acids are typically classified as similar to one another as "hydrophobic" or "hydrophilic" amino acids, and / or as having "polar' or "non-polar” side chains. Substitution of one amino add for another of the same type may often be considered a "homologous” substitution.

[0279] Identity. As used herein, the term “identity" refers to the overall relatedness between polynucleotide molecules DNA molecules and / or RNA molecules) and / or between polypeptide molecules. In some embodiments, polynucleotide molecules (eg., DNA molecules and / or RNA molecules) and / or between polypeptide molecules are considered to be "substantially Identical" to one another If their sequences are at least 80%, 85%, 90%, 95%, 96%, 97%, 98%, or 99% Identical. Calcination of the percent Identity of two nudeic add or polypeptide sequences, for example, can be performed by aligning the two sequences for optimal comparison purposes (e.g., gaps can be introduced in one or both of a first and a second sequence for optimal alignment and non-ldentlcal sequences can be disregarded for comparison purposes). In certain embodiments, the length of a sequence aligned for comparison purposes is at least 30%, at least 40%, at least 50%, at least 60%, at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 95%, at least 96%, at least 97%, at least 98%, at least 99%, or substantially 100% of the length of a reference sequence. The nucleotides at corresponding positions are then compared. When a position In the first sequence is occupied by the same residue (e.g., nudeotide or amino add) as the corresponding position in the second sequence, then the molecules are identical at that position. The percent identity between the two sequences is a function of the number of identical positions shared by the sequences, taking into account the number of gaps, and the length of each gap, which needs to be introduced for optimal alignment of the two sequences. The comparison of sequences and determination of percent identity between two sequences can be accomplished using a mathematical algorithm. For example, the percent Identity between two nudeotide sequences can be determined using the algorithm of Meyers and Miller, 1989, which has been incorporated into the ALIGN program (version 2.0). In some exemplary embodiments, nucleic acid sequence comparisons made with the ALIGN program use a PAM120 weight residue table, a gap length penalty of 12 and a gap penalty of 4. The percent identity between two nudeotide sequences can, alternatively, be determined using the GAP program in the GCG software package using an NWSgapdna.CMP matrix.

[0305] Malaria is a mosquito-borne infectious cfisease caused by single-celled eukaryotic Plasmodium parasites that are transmitted by the bite of Anopheles app. mosquitoes (Phillips, M., etai. Malaria. Nat Rev Dis Primers3, 17050, 2017, which is incorporated herein by reference in its entirety). Mosquitoes that transmit malaria must have been infected through a previous blood meal taken from an infected subject (e.g., a human). When a mosquito bites an infected subject a small amount of blood is taken in containing Malaria parasites. The infected mosquito can then subsequently bite a non-infected subject, infecting the subject

[0306] Malaria remains one of the most serious infectious diseases, causing approximately 200 million dinical cases and 500,000-600,000 deaths annuaHy. Although significant effort has been invested in developing therapeutic treatments for malaria, many malaria parasites have developed resistance to available therapeutics. According to Malaria Eradication Research Agenda Initiative, malaria eradication will only be achievable through effective vaccination.

[0307] In 2015, the European Medicines Agency gave a positive review to a malaria vaccine candidate known as *RTS,S", a milestone in malaria vaccine development. In 2019, the World Health Organization launched pilot programs that provide RTS,S to children at least 5 months of age in parts of three sub-Saharan African countries. RT5,S / AS01 Is an adjuvanted protein subunit vaccine that consists of a portion of the major repeat region and the C- terminus of CSP from Plasmodium falciparum fused to the Hepatitis B surface antigen (HBsAg). The vaccine is a mix of this ACSP-HBsAg compound with HBsAg that forms virus-like particles (RTS,S / AS01; Mosquirix™). RTS,S is administered according to a regimen that requires four doses: an initial 3-dose schediie given at least 1 month apart, and a 4th dose 15-18 months after dose 3 (see, for example, Vandoolaeghe & Schuerman Expert Rev Vaccines. 15:1481, 2016; PATH_MVI_RTSS_Fact Sheet_042019, each of which Is incorporated herein by reference In its entirety). Reports indicate that RTS,S protects approximately 30% to 50% of children from clinical disease over 18 months. RTS,S has been reported to induce protective antibody and CD4+ T-cell responses, but only negligible CD8+ T cell responses (see, for example, Moris et al. Hum Vaccki Immunother 14:17, 2018, which is incorporated herein by reference in Its entirety). Phase III studies of RTS,S delivered as a three-dose series with a booster after 1 yr (year) showed moderate vaccine efficacy in children aged 5 to 17 months preventing 36% of clinical malaria cases over the ful study period with a median follow-up of 4 yrs, with a range of 20% in high to 66% In low transmission settings. Furthermore, published literature suggests that protection wanes over time InducHng reports of potential negative efficacy after 5 yrs In children with high malaria exposure (Olotu et al. 2016, N. Engl. J. Med. 374:2519-29)which is incorporated herein by reference in its entirety).Thus, an effective malaria vaccine remains an unmet medical need of critical importance for global health.Lifecycle

[0308] During a blood meal, infected mosquitos inject, along with their anticoagulating saliva, sporozoites known as the liver stage of Plasmodium spp. Sporozoites journey through the skin, and if successful, into hepatocytes of the liver. This journey happens very quickly; it can be completed within only a few minutes (Sinnis et al., Parasite! Int. 2007 Sep;56(3): 171-8, which is incorporated herein by reference in its entirety). This is a time known to be a stage during which it is challenging for the host immune system to mount an effective response against the parasite, as only a small number (thought to be a few hundred at maximum) of sporozoites are injected by the mosquito, with a small fraction of those parasites establishing Infection In the liver (Flores-Garda et al., mBio. 2018 Nov 20;9(6):e02194-18, which is incorporated herein by reference in its entirety).

[0309] When moving from an inoculation site in the skin to the liver, sporozoites traverse host ceHs (Mota et al., Science 2001 Jan 5;291(5501): 141-4). Sporozoites traverse different types of host cells at the dermis, including fibroblasts and phagocytes (Amino et al.. Cell Host Microbe. 2008 Feb 14;3(2):88-96, which is incorporated herein by reference in its entirety), and the liver sinusoidal barrier, containing liver endothelial cells and Kupffer cells (Frevert et al., PLoS Biol 3(6): el92. 2005, which is incorporated herein by reference In its entirety) and sinusoidal endothelial cells (Tavares et al., J Exp Med 2013 May 6;210(5):905-15, which is Incorporated herein by reference In Its entirety), in order to gain access to hepatocytes. Sporozoites preferentially traverse cells with low-sulfated heparin sulfate proteoglycans (HSPGs) but preferentially Invade cells with high-sulfated HSPGs (Coppi et al., Cell Host & Microbe 2, 316-327, November 2007, which Is Incorporated herein by reference In Its entirety).

[0310] Cell traversal was first observed as non-phagocytic entry of P. Aergite / sporozoltes Into macrophages followed by "escape" from these cels (Vanderberg et al., J. Euk. Microbiol. 37:528-536, 1990, which is Incorporated herein by reference In Its entirety). The biochemical, biophysical, and stepwise processes of traversal are still being explored. However, It has been suggested by electron microscopy that host cell rupture occurs upon entry and exit from the host cell (Mota et al., 2001; Tavares et al., 2013, each of which is incorporated herein by reference in its entirety). It has also been shown that P. yoetiispotozoktes can enter hepatocytes via a transient vacuole and that host membrane rupture occurs upon cell exit rather than cell entry (Risco-Castillo et al., Cell Host Microbe 2015 Nov ll;18(5):593-603, which is incorporated herein by reference in its entirety).

[0311] Sporozoites also traverse hepatocytes before establishing a productive hepatocyte infection (Mota et al., 2001, which is incorporated herein by reference in its entirety). Several possibilities emerged as to why this occurs. The first hypothesis suggested that migration through hepatocytes primes parasites for invasion by activating apical exocytosis (Mota et al., Nat Med 2002 Nov;8(ll): 1318-22, which is incorporated herein by reference in Its entirety). The second theory suggested that traversal releases hepatocyte growth factor (HGF), making neighboring hepatocytes more susceptible to infection (Carrolo et al., Nat Med . 2003 Nov;9(ll):1363-9, which is incorporated herein by reference in its entirety). Lastly, other studies suggest that it takes some time for sporozoites to switch off the machinery for traversal and activate invasion machinery (Amino et al., 2008, Coppi et al., 2007, each of which is incorporated herein by reference in its entirety), and that traversal primarily functions to penetrate cell banners and avoid phagocytosis en route to the liver (Amino et al., 2008, Coppi et al., 2007, Tavares et al., 2013, each of which is incorporated herein by reference in its entirety).

[0312] Although it has been shown that sporozoites traverse human cells (Behet et al., Malar J 2014 Apr 5;13: 136; Cha et al., J Exp Med 2015 Aug 24;212(9):139M03; Dumoulin et al., PLoS One 2015 Jun 12;10(6):e0129623; van Schaijk et al., PLoS ONE, 3 (10). e3549 2008, each of which is incorporated herein by reference in its entirety), the molecular basis for the traversal process is largely unstudied. Antibodies against circumsporozoite protein (CSP) impair traversal (Dumoulin et al., 2015, which is incorporated herein by reference in its entirety), but this is likely due to inhibition of motility rather than a direct effect (Cha et al., J Exp Med 2016 Sep 19;213(10):2099-112, which is incorporated herein by reference in its entirety). Furthermore, antibodies induced by CPS-immunication (chloroquine prophylaxis with sporozoites) may target CSP and interfere with cell traversal (Behet et al., 2014, which is Incorporated herein by reference in its entirety). Recently it was shown that glyceraldehyde 3- phosphate dehydrogenase (GAPDH) on the parasite surface Interacts with CD68 on Kupffer cells during traversal (Cha et al., 2015, Cha et al., 2016, each of which is incorporated herein by reference in its entirety).

[0313] In rodent malaria parasites such as P. berghei, two sporozoite miaroneme proteins have been identified that appear to be essential for cel traversal (sporozoite microneme protein essential for cell traversal [SPECT1; Ishino et al., PLoS Biol., 2 (2004), pp. 77-84, which is incorporated herein by reference in its entirety] and SPECT2 [Ishino et al., Cell. Microbiol., 7 (2005), pp. 199-208, which is incorporated herein by reference in its entirety], also called perforin-like protein 1 [PLP1] [Kaiser et al., Mol. Blochem. Parasitol., 133 (2004), pp. 15-26, which is Incorporated herein by reference In Its entirety]. Even though genetic disruption of SPECT1 or SPECT2 rendered sporozoites unable to traverse murine cells, they still invaded hepatocytes in vitro (Ishino et al., 2004, Ishino et al., 2005, each of which Is Incorporated herein by reference in its entirety). When Injected Into rodents, sporozoites lacking SPECT1 or SPECT2 were Impaired for liver infection, but a small number of sporozoites could stIH establish liver infection that resulted in subsequent patency. However, depletion of Kupffer cells aflowed mutants to establish liver infection at levels comparable with wild-type parasites (Ishino et al., 2004, Ishino et al., 2005, each of which Is incorporated herein by reference In its entirety). This data suggests that traversal by rodent-infecting sporozoites Is Important for navigating through the sinusoidal layer, but not for hepatocyte invasion, malarial exoerythrocytic forms development, or growth within erythrocytes (Ishino et al., 2004, Ishino et al., 2005, each of which is Incorporated herein by reference In its entirety).

[0314] The ortholog of SPECT2 in P. yoeSi, PLP1, has been shown to play a role in cell traversal. Although this protein is not required for hepatocyte entry, it plays a role in egress from transient vacuoles during traversal (Risco- Castillo et al., 2015, each of which is incorporated herein by reference in its entirety). Thus, sporozoites that infect rodents can traverse host cells by generating a vacuole at the entry step and use a perforin-like protein (e.g., SPECT2 / PLP1) to escape from this compartment and / or a host cell, during cell exit.

[0315] Once sporozoites have Invaded liver cells, they dfferentiate into merozoites, a replicative form of the parasite. Within a few days, a single sporozoite can lead to 5,000-10,000 merozoites. Merozoites bud from the host hepatocyte in structures called merosomes, which contain up to a thousand merozoites and are hidden from host immune responses due to their host membrane composition. These merosomes ultimately release merozoites that mix freely with the host cytoplasm and appear in the blood stream, where they invade red blood cells and begin the blood stage of infection, characterized by fast asexual replication and clinical presentation. Within a small number of days, hundreds of thousands of parasites can be present in the blood.

[0316] Plasmodium spp. parasites gain entry into red blood cells through specific ligand-receptor interactions mediated by proteins on the surface of the parasite that interact with receptors on the host erythrocyte (mature redblood cell) or reticulocyte (immature red blood cell), whereas P. / atoparumcan invade and replicate in erythrocytes and reticulocytes, P. wVaxand other species predominantly invade reticulocytes, which are less abundant than erythrocytes. Most of the erythrocyte-binding proteins or reticulocyte-binding proteins that have been associated with invasion are redundant or are expressed as a family of variant forms; however, for P. falciparum, two essential red blood cell receptors (basigin and complement decay-accelerating factor (also known as CD55)) have been identified.

[0317] P. mar and P. ovale can also enter a dormant state in the liver, the hypnozoite.

[0318] The invasion of a red blood cell by the merozoite involves interactions of multiple parasite derived proteins (e.g., ligands) with red blood cell (RBC) proteins (e.g., receptors) (Weiss et al., Pios Path., 2015 Feb 27; 10.1371, which is Incorporated herein by reference in its entirety). The invasion process begins by the merozoite first attaching to the RBC. Merozoite-RBC Interaction Is further strengthened through merozoite surface protein- 1 (MSP1) and unknown RBC proteins, causing some deformation of the RBC surface. After the deformation, interaction of merozoite EBA and Rh protein families (excluding Rh5) with host receptors like CR1 lead to actin-dependent deformation of the RBC membrane and reorientation of the merozoites apical end onto the RBC surface (Geoghehan et al., Nat Commui., 2021 June 15;10.1038 which is incorporated herein by reference in its entirety). This deformation event increases the surface area of interaction between merozoite and RBC membranes, an interaction which can be stabilized by an Rh5 invasion complex comprising Plasmodium thrombospondin-related apical merozoite protein (PTRAMP), cystelne-rlch small secreted (CSS), cysteine-rich protective antigen (CyRPA), Rh5-interactlng protein (Rlpr) and Rh5. This Rh5 invasion complex including the five proteins is referred to as the PCRCR complex.

[0319] The creation of the PCRCR complex begins in the endoplasmic reticulum, where Its constituents cystelne-rlch small secreted (CSS) protein and Plasmodium thrombospondin-related apical merozoite protein (PTRAMP) Interact to form a heterodimer referred to as PTRAMP-CSS. PTRAMP-CSS Is trafficked to a secretory organelle called the microneme, where CSS interacts with Rh5-interactlng protein (Rlpr) and cystelne-rlch protective antigen (CyRPA) to form a tetrameric complex called PCRC. At some point after deformation occurs, the merozoite Initiates a polarized secretion process that allows the mlcronemal PCRC complex opportunity to Interact with rhoptry protein Rh5, forming the pentameric complex PCRCR. The PCRCR complex, through Rh5, can then bind a host cell receptor, called basigin, broadly across the merozoite-RBC Interphase. PCRCR binding to basigin creates a stable and Irreversible platform between the apical end of the merozoite and the deformed RBC surface, allowing Rh5 and Rlpr to embed into the RBC membrane (Scally et al., Nat Microb., 2022 May 4, which is incorporated herein by reference in its entirety). Once the merozoite-RBC interaction is secured, an open connection between the merozoite's apical tip and the RBC surface is formed which acts as a conduit for Ca2* to flow into the RBC, and for merozoite derived invasion proteins, such as AMA1 and RON2, to help establish the moving junction (Srinivasan et al., Proc Natl Acad Sd., 2011 Jul 25;13275-80, which is Incorporated herein by reference in its entirety). It Is through this moving junction that the parasite, utilizing its actin-myosin dependent gliding motility, propels itself inside the RBC and establishes a parasitopherous vacuole within which the parasite grows and replicates.

[0320] It has been shown that Rh5 binds basigin with higher affinity when complexed with CyRPA and Ripr to form the RCR complex, and has the highest affinity for basigin when part of the PCRCR complex (Wong et al., Nature., 2019 and Scally et al., Nat Microb., 2022 May 4, each of which are incorporated herein by reference in its entirety).

[0321] Merozoites that egress from red blood cells can invade other red blood cells to continue to the asexual blood stage of the parasite lifecycle. A small percentage of schizonts are already committed to a different fate andmerozoites from these schizonts, following invasion of a new red blood cell, will differentiate into the sexual forms on the parasite's life cycle; either male or female, gametocytes. Gametocytes are taken up by the mosquito vector during blood feeding. In the gut of the mosquito, male gametocytes undergo 3 rapid rounds of mitosis to form 8 flagellate microgametes. Female gametocytes mature into macrogametes, egressing from their red blood cell. Male microgametes are motile forms with flagellae and seek the female macrogamete. The male and female gametocytes fuse, forming a diploid zygote, which matures and differentiates into an ookinete; this motile form secretes chitinases and other lytic proteins such as CelTOS in order to disrupt and traverse through the peritrophic matrix and traverse the midgut epithelium to reach the basal lamina where it further differentiates and matures as an oocyst Oocysts mature over approximately 10 days (depending on the temperature), replicating to form sporozoites that egress the mature oocyst Into the hemocoel of the mosquito. Thousands of sporozoites form in a single oocyst and become randomly distributed throughout the hemocoel. It is thought that sporozoites are passively circulated through the mosquito haemolymph until they encounter the salivary glands, where they actively invade the glands. Following invasion of the salivary gland, sporozoites are re-programmed via an unknown mechanism to prepare for Iver Invasion. Evidence of this reprogramming has been demonstrated by the inability of midgut sporozoites (directly from oocysts) to invade hepatocytes, and also by the fact that sporozoites which have successfully invaded a salivary gland are unable to re-invade another salivary gland if presented one. Salivary gland sporozoites alter mosquito behavior and salivary gland function, as less saliva is produced resulting In an Increase In mosquito probing behavior, increasing the chances of transmission to a human host via a mosquito bite and continuing the human host's phase of this parasite's life cyde.

[0322] P. vivax anti P. ovale can also enter a dormant state in the liver, the hypnozoite.

[0323] One particular challenge associated with mounting an immune response capable of clearing sporozoites before a liver infection has been established Is that the most abundant and Immunogenic protein on the sporozoite surface, the circumsporozoite protein (CSP), is only exposed to the immune system in small quantities and for a short duration of time due to the variably low inoculum from the mosquito and the kinetics of hepatocyte infection after inoculation. Furthermore, after liver infection is established, the parasite differentiates into a stage during which it no longer expresses CSP and hstead has a different mosaic of surface antigens, making the parasite Invisible to, e.g., any memory immune response directed towards the liver stage. The early stages of parasite exposure to the human host create a short window for the innate and memory immune systems to generate a response that is capable of clearing all parasites before infection is established. The clinical significance of immune evasion by sporozoites are high at this point, as all it takes is a single sporozoite to invade a hepatocyte and produce as many as 10,000 blood stage parasites (merozoites) capable of invading, replicating within, and lysing red blood cells (Shears et al., jproteome. 2019 July 23; 3404-3418, which Is Incorporated herein by reference In its entirety). These initial stages of the parasite's life cyde in a human host help to demonstrate the difficulty in targeting liver stage parasites for therapeutic intervention and the low efficacy seen with current vaccines. (Oluta A. et al., N Engl J Med. 2016 June 30;216:374, which is incorporated herein by reference in its entirety). Therefore, targeting the blood stage of Plasmodium spp. infection offers a promising approach for reducing deaths caused by malaria.

[0324] Malaria symptoms typically develop 4-8 days after initial red blood cell invasion. Replication cyde of merozoites within the red blood cells continues for 36-72 hours, until hemolysis, releasing the merozoites for another round of red blood cell infection. Thus, in synchronous infections (infections that originate from a single infectious bite), fever occurs every 36-72 hours, when infected red blood cells lyse and release endotoxins en masse.

[0325] Some drugs that prevent Plasmodium spp. invasion or proliferation in the liver have prophylactic activity, drugs that block the red blood cell stage are required for the treatment of the symptomatic phase of the disease, and compounds that inhibit the formation of gametocytes or their development in the mosquito (including drugs that kill mosquitoes feeding on blood) are transmission-blocking agents (Phillips, et al. Malaria. Nat Rev Dis Primers3, 17050 (2017), which is incorporated herein by reference in its entirety). B. Genome

[0326] Since completion of the first sequence of P. falciparum 3D7 genome in 2002, genomic research on malaria parasites has rapidly advanced. Except for a short diploid phase after fertilization in the mosquito midgut, Plasmodium spp. parasites are haploid throughout their life cycle. The genomes of (Afferent species range from 20 to 35 megabases, contain 14 chromosomes, a circular plastid genome of approximately 35 kilobases, and multiple copies of a 6 kilobase mitochondrial DMA. Comparison of genomes from different species showed that homologous genes are often found in synthetic blocks arranged in different orders among different chromosomes.

[0327] The adenine-thymine (AT) content of Plasmodium spp. can also be very different, e.g., ~80% AT in P. falciparum, P. reichenowi, and P. gaHinaceunr, ~75% AT in rodent malaria parasites; and ~60% AT in P. vivax, P. knowtesi, and P. cynomolgi. AT content is often higher in introns and intergenic noncoding regions than in proteincoding exons, with an average of 80.6% AT for the whole P. fakiparum genome versus 86.5% for noncoding sequences. The high AT content of P. fakiparum reflects large numbers of low-complexity regions, simple sequence repeats, and microsatellites, as well as a highly skewed codon usage bias. Polymorphisms of AT-rich repeats provide abundant markers for linkage mapping of drug resistance genes and for tracing the evolution and structure of parasite populations.

[0328] Malaria parasite genomes carry multigene families that serve important roles in parasite interactions with their hosts, including, for example, antigenic variation, signaling, protein trafficking, and adhesion. Among the gene families, genes encoding P. fakiparum erythrocyte membrane protein 1 (P / EMP1) have been studied most extensively. Each Individual P. falciparum parasite carries a unique set of 50 to 150 copies of the vargene In Its genome, where switches of gene expression can produce antigenic variation. P / EMP1 plays an Important role in the pathogenesis of clinical developments such as in cerebral and placental malaria, in which it mediates the cytoadherence of infected red blood cells (iRBCs; infected erythrocytes) in the deep tissues. Different P / EMP1 molecules bind to various host molecules, including o2 -macroglobulin, CD36, chondroitin sulfate A (CSA), complement Iq, CR1, E-selectins and P-selectins, endothelial protein C receptor (EPCR), heparan sulfate, ICAM1, IgM, IgG, PECAM1, thrombospondin (TSP), and VCAM1. Such binding leads to activation of various host inflammatory responses. Hemoglobinopathies, including the hemoglobin C and hemoglobin S trait conditions, interfere with P / EMP1 display In knob structures of the IRBCs. This poor dsplay of P / EMP1 on the host cell surface offers protection against malaria by reducing the cytoadherence and activation of inflammatory processes that promote the development of severe disease.

[0329] Members of the large Plasmodium Interspersed repeat (pir) multigene family are named differently by parasite species, for example, yir in P. yoelii, bir in P. berghei, vir in P. vivax. Several P. falciparum gene families (stevor, rif, and P / MC-2TM) are classified with pir by their similar gene structures, which characteristically Include a short first exon, a long second exon, and a third exon encoding a transmembrane domain. In a recent study, the pir genes from P. chabaudi^df) were shown to be expressed in different cellular locations, within and on the suface of iRBCs, and in merozoites. Malaria parasites devote large portions of their genomes to gene families that ensureevasion of host immune defenses and protection of molecular processes essential to infection. These famiies emphasize the importance of research on their roles in parasite-host interactions and virulence, despite the difficulties inherent to their investigation.

[0330] An additional, exemplary polymorphic gene family comprises a group of 14 genes encoding proteins with six cysteines (6-Cys). These proteins often localize on the parasite surface interacting with host proteins and are expressed at different parasite developmental stages. 6-Cys proteins also demonstrate diverse functions and have been shown to play roles in, for example, parasite fertilization, mating interactions, evasion of immune responses, and invasion of hepatocytes. The proteins expressed in asexual stages are generally polymorphic and / or under selection, suggesting that they could be targets of the host immune response; however, their functions in parasite development remain largely unknown.

[0331] Plasmodium genomes can be highly polymorphic. Early studies demonstrated polymorphisms involving tens to hundreds of kilobases and that the chromosome structure in P. falciparum is largely conserved in central regions but extensively polymorphic is both length and sequence near the telomeres. Much of the subtelomeric variation was explained by recombination within blocks of repetitive sequences and families of genes.

[0332] The frequency of simple sequence repeats (microsatellites) in P. faldparum is estimated to be approximately one polymorphic microsatellite per kb DNA. Without wishing to be bound by any one theory, this high rate may reflect the AT -rich nature of the genome. Mlcrosatellltes seem to be less frequent In other Plasmodium species that have genomes with lower AT contents. In addition to the highly polymorphic and repetitive structure of Plasmodium genomes, there are also large numbers of Single Nucleotide Polymorphisms (SNPs) and Copy Number Variations (CNVs) (Su eta!., Plasmodium tenomks and Genetics: New Insights Into Malaria Pathogenesis, Drug Resistance, Epidemiology, and Evolution. Clin Microbiol Rev. 2019 Jul 31;32(4), which is Incorporated herein by reference In its entirety).C. Plasmodium Proteins1. Rh5 Invasion Complex Polypeptides Rh5

[0333] Rh5 is found In P. faldparum, but not in all other species of Plasmodium that infect humans which contain proteins that perform an analgous function as Rh5. Rh5 orthologues are also found in other species belonging to the Lavarenia subgenus, which includes parasites that infect chimpanzees and gorillas, indicating a unique role in P. falciparum invasion of human erythrocytes. See, e.g., Ragotte, et al. Trends Parasitol. 36(6) 2020, which is incorporated herein by reference in its entirety. Rh5 is expressed during the mature schizont stages and localizes to the Rhoptry, a polarized secretory organelle of P. faldparum. Rh5 is a protein that is secreted during the invasion process and is believed to be essential for the completion of parasite invasion of the erythrocyte. Rh5 functions downstream of intial parasite attachment to the erythrocyte surface and deformation of the erythrocyte membrane. Upon secretion, Rh5 binds to erythrocyte surface protein basigin, creating an attachment and a stable platform for downstream receptor-ligand interactions and associated invasion invents to occur. Bindng of Rh5 to basigin is also required for the induction of a spike in calcium within the erythrocyte, which is blocked when merozoites attempt to invade in the presence of anti-Rh5, anti-Ripr, or anti-baslgin antibodies or soluble basigin (See, e.g., Ragotte (2020), which is incorporated herein by reference in its entirety).

[0334] Rh5 can interact with multiple proteins to form complexes. The affinity of Rh5 for basigin varies based on which complex Rh5 is in. For example, Rh5 can complex with CyRPA and Ripr to form an elongated protein trimer,called RCR, on the merozoite surface that binds to erythrocyte surface protein basigin with higher affinity than Rh5 alone. (See, e.g., Ragotte (2020) and Wong (2019), each of which are incorporated herein by reference in its entirety). Rh5 has its highest affinity to basigin when interacting with PTRAMP, CSS, Ripr, and CyRPA in a pentameric complex known as PCRCR. See, Scally (2022).

[0335] Rh5 is a 63 kDa protein expressed during the mature schizont stage. It is processed and cleaved to a 45 kDa form which is shed by the parasite. The structure of Rh5 reveals a kite-like architecture formed from the coming together of two three-helical bundles. See, e.g., Ragotte (2020), which is incorporated herein by reference in its entirety.

[0336] Rh5 sequences are known (see, e.g., UnIProt accession numbers A0A159SK44, A0A159SK99, A0A159SKS8, A0A159SKW8, A0A159SL23, A0A159SL78, A0A159SL96, A0A159SLM7, A0A159SMC8, A0A159SMR9, A0A161FQT0, A0A1B1UZE2, A0A1B1UZE4, A0A1B1UZE5, A0A346RCI1, A0A346RCJ0, A0A346RCJ2, A0A346RCJ3, A0A346RCJ4, A0A346RCK4, A0A346RCK5, A0A346RCK6, A0A346RCK9, B2L3N7, Q8IFM5, each of which is incorporated herein by reference in its entirety), and exemplary Rh5 amino add sequence is provided in Table 1. Rh5-lnteractino Protein fRiorl

[0337] Rh5-lnteracting Protein (Ripr) is an approximately 120 kDa protein and localized to mkronemes during the schizont stage of the Plasmodium life cycle. The full-length 120 kDa protein is processed into two fragments of similar size, an N-termlnal fragment (Indudlng EGF domains 1 and 2) and a C-termlnal fragment (Indudlng EGF domains 3-10). Ripr colocalizes with Rh5 and CyRPA during parasite invasion at the junction between merozoites and erythrocyte. Parasites with conditional knockouts of fliRipr induce membrane deformation, but cannot complete Invasion (See, e.g., Ragotte (2020) which is incorporated herein by reference in Its entirety).

[0338] Ripr sequences are known (see, e.g., UniProt accession numbers A0A193PDI9, A0A193PDK3, A0A193PDK8, A0A193PDL3, A0A193PDL9, A0A193PDP4, A0A193PDQ8, A0A193PE01, A0A193PE05, A0A193PE07, 097302, A0A193PE17). Exemplary Ripr amino add sequences are provided In Table 1.Cvstelne-Rich Protective Antigen fCvRPAI

[0339] Cysteine-Rich Protective Antigen (CyRPA) is a 43 kDa protein with a predicted N-terminal secretion slgial. CyRPA is a critical mediator of an Invasion multi-protein complex consisting of Rh5 and Ripr, known as RCR, that Improves Rh5 affinity to the erythrocytic basigin receptor. The ability of CyRPA to make limited contact with Ripr and Rh5 is thought to permit the disassociation of Rh5 and Ripr from this complex so they can be inserted into the erythrocyte membrane, helping to further stabilize the contact between parasite and erythrocyte. CyRPA also plays a role in the PCRCR complex which further increase Rh5 affinity to basigin. CyRPA mediated Rh5 binding to basigin is important for stabilizing the parasite-erythrocyte membrane interaction which allows downstream invasion events, like Ca2+increase In the erythrocyte cytosol and establishment of tight / movlng junctions, to occur. CyRPA is highly conserved, with only a single SNP above 5% prevalence in the general population. CyRPA is important for invasion (as conditional knockdown causes the loss of invasion activity), and CyRPA has poor sero-reactivity from natural exposure (See, e.g., Ragotte (2020) and Cowman (2018) each of which is incorporated herein by reference in its entirety).

[0340] CyRPA sequences are known (see, e.g., Uniprot accession number A0A2S1Q7P0, A0A2S1Q7P5, A0A2S1Q7Q4, Q8IFM8, each of which is incorporated herein by reference in its entirety). Exemplary CyRPA amino add sequence is provided in Table 1.Ptesmtxi'u / nThrombowondic- Related Apical Merozoite Protein (PTRAMP)

[0341] Plasmodium thrombospondic-related apical merozoite protein (PTRAMP) is a 352 amino add protein that localizes to developing micronemes and relocates to the merozoite surface upon invasion and is understood to be important for host cell invasion by P. falciparum. Orthologs to the gene encoding PTRAMP is present in all malaria parasite spedes examined, indicating a conserved role in host invasion and making it an opportune target for therapeutic intervention. Important to vaccine approaches, PTRAMP appears to exhibit both linear and conformational epitopes, which would give the immune system the opportunity to utilize both B cell receptors and T cell receptors for recognition and activation when exposed to PTRAMP (Alvaro et al., Malaria Jou., 2010 Oct. 13;10.1186, which is Incorporated herein by reference in its entirety). PTRAMP can interact with cysteine-rich small secreted (CSS) protein to form a heterodimer known as PTRAMP-CSS which in turn can, through CSS, Interact with Ripr and CyRPA to form a tetrameric complex called PCRC, that ultimately Interacts with Rh5 forming a pentameric complex PCRCR which enhances Rh5 binding to host baslgin and Is important for P. falciparum to invade RBCs. Nanobodies against PTRAMP inhibit merozoite significantly reduce merozoite invasion and give evidence to the potential efficacy therapeutically targeting PTRAMP could provide (Scally et al., Nat Microb., 2022 May 4, which Is incorporated herein by reference In Its entirety).

[0342] PTRAMP sequences are known (see, e.g., Uniprot accession number [Q8I5M8]). Exemplary PTRAMP amino acid sequence is provided in Table 1.Cvstelne-Rlch Small Secreted Protein (CSS)

[0343] Cysteine-rich small secreted protein (CSS) Is a 290 amino add cryptic 6-Cys protein comprised of two degenerate 6-Cys domains. Proteins belonging to this family commonly mediate extracellular protein-protein interactions, a role that has been confirmed to occur In P. falciparum. CSS is capable of biding both PTRAMP and Ripr. CSS Interaction with PTRAMP occurs in the endoplasmic reticulum, whereas CSS interaction with Ripr occurs after trafficking to the micronemes. CSS Interaction with PTRAMP and Ripr are involved in Invasion and the formation of the PCRC complex, which is capable of complexing with Rh5 and enhancing Rh5's Interaction with baslgin. Similar to PTRAMP, nanobodies against CSS have been showing to Inhibit Invasion, indicating Its role in the invasion process likely thought its partldpation in the PCRCR complex. Nanobodies which inhibit CSS binding to PTRAMP or Ripr do not inhibit invasion, confirming the interaction of these proteins before exposure to the merozoite surface. The Inhibitory activity of nanobodies against CSS are thought to occur by potentially blocking Ripr and / or Rh5 insertion into the RBC membrane and / or disrupting the conformational changes of the PCRCR complex required for invasion, although the exact mechanism of inhibition is not entirely known. Contrary to this observation and of immunological significance, polydonal antibodies to CSS and PTRAMP do not exhibit any neutralizing activity, indicating the immunodominance of non-neutralizing epitopes of CSS and PTRAMP that bias antibody selection (in a natural setting) away from epitopes with neutralizing capability. This observation provides the molecular rationale for identifying invasion inhibitory epitopes on CSS and PTRAMP which are highly conserved in P. falciparum, for usage in vaccine platforms. See Cowman (2022).

[0344] CSS sequences are known (see, e.g., Uniprot accession number [Q8IM47]). Exemplary CSS amino acid sequence is provided in Table 1.

[0345] In some embodiments, a Plasmodium CSS polypeptide or antigenic portion thereof comprises a serine at position 30, as numbered according to SEQ ID NO: 5. As exemplary CSS amino add sequence comprising a C30S mutation is provided in Table 1.£113

[0346] P113 is a glycosylphosphatidylinositol (GPI)-linked protein that interacts directly with the N terminus of unprocessed Rh5, which has been thought to provide a mechanism by which the Rh5 invasion complex is tethered to the merozoite surface. However, recent findings have shown that P113 may not be essential for P. falciparum growth, as other proteins and complexes exist that can perform the Rh5 membrane tethering function of P113. See, e.g., Ragotte (2020) and Scally (2022). In addition to its canonical role, P113 is present in the paristopherous vacuole (PV) and has been shown to interact with parasite export complexes like PTEX and EPIC, which are important for the transport of parasite effector proteins across the paristopherous vacuole membrane (PVM). P113 has also been shown to play a role in PVM architecture, as the deletion of this gene leads to a disruption In PVM morphology. P113 orthologues are found in all Plasmodium species sequenced thus far, which is suggestive of common and conserved functions (Bullen et al. (2022) Molecular Microbiology 117:1245-1262, which is incorporated herein by reference in its entirety). Despite this fact, in P. berghei, Pl 13 knockout parasites were viable, indicating the protein was not essential for asexual blood stage growth and invasion. The knockout parasites do, however, display defects In natural sporozoite transmission, leading to delayed patency in Infected mice (Offeddu et al. (2014) Mol. Blochem. Parasitology 193: 101-109, which is incorporated herein by reference in its entirety).

[0347] Plasmodium Pl 13 sequences are known (see, e.g., Uniprot accession number Q8ILP3).

Additional Plasmodium Proteins

[0348] Plasmodium parasites are known to express various proteins at different stages of their lifecycles. Exemplary malarial proteins are described below, and exemplary amino add sequences are provided in Table 2. Circumsporozoite Protein fCSPI

[0348] Circumsporozoite protein (CSP) is a multifunctional protein that is involved in Plasmodium life cycle, as it is required for the formation of sporozoites in the mosquito midgut, the release of sporozoites from the oocyst, invasion of salivary glands, attachment of sporozoites to hepatocytes in the liver, and sporozoite invasion of hepatocytes (see, e.g., Zhao et al. (2016) PLoS ONE 11(8): e0161607, which is incorporated herein by reference in its entirety). CSP is present in all Plasmodium spedes, and although variation exists in the amino add sequence across species, the overall domain structure of a central repeat region and nonrepeat flanking regions is well conserved (see, e.g., Zhao et al. (2016) PLoS ONE 11(8): e0161607; Wahl et al. (2022) J. Exp. Med. 219: e20201313, each of which is incorporated herein by reference in its entirety). CSP sequences are known (see, e.g., UniProt accession numbers A0A2L1CF52, A0A2L,lCF88, C6FGZ3, C6FH2,7 C6FHG7, M1V060, M1V0A3, Ml V0 B0,M1V0C4, M1V0E0, M1V9I4, M1VFN9, M1VKZ2, P02893, Q5EU9, Q5BK2, Q5BK8, Q5EIL3, Q5EIL5, Q5BL8, Q5R2L2, Q7K740, Q8I9G5, Q8I9J3, Q8I9J4). Exemplary CSP amino acid sequences are provided in Table 2. E140

[0350] E140 is found in every Plasmodium species for which a genomic sequence is available, and is well conserved, with amino add identity ranging from 34-92% among spedes. See, e.g., Smith , et al. PLoS one 15.5 (2020): 60232234; http: / / doi: 10.1371 / joumal.pone.023223; and U.S. Patent Publication No. US 2019 / 0117752; each of which are incorporated herein by reference in their entirety. E140 is also highly conserved (95-99%) in P. falciparum sir aixxs isolated from different locations around the world, and exhibits a low mutation frequency. E140 is expressed at different life stages of malaria parasites (spedfically, E140 has been detected in sporozoites, liver, and blood stage parasites).

[0351] Protein structure algorithms predict that the E140 protein has five transmembrane domains, presumable spanring a parasite or host-derived membrane. E140 displays distinct patterns of protein expression In mature sporozoites, late liver, and late schizont stages. It traffics to the anterior and posterior ends of the sporozoite, the parasitophorous vacuole space of the late liver stage and around developing merozoites in the late schizont stage. It is also known to be expressed In mature salivary gland sporozoites as well as oocyst-derived sporozoites and oocysts.

[0352] E140 sequences are known (see, e.g., UnIProt accession numbers A0A650D649, A0A650D653,A0A650D672, A0A650D687, AOA650D690, A0A650D694, A0A650D6A3, A0A650D6B8, A0A650D6L3, A0A650D6L7, Q8I299, each of which Is incorporated herein by reference In its entirety), and an exemplary E140 amino add sequence Is provided In Table 2.CeiTOS

[0353] CeiTOS Is required for sporozoite traversal through Kupffer cells during the liver invasion process.CeiTOS forms a pore from within the cell, allowing for sporozoite egress into the liver. Antibody epitopes have been characterized from Immunized mice and infected human populations (PFand PV). In mouse studies, Immunization with CeiTOS has been shown to provide protection and against challenge. Vaccination with CeiTOS may generate antibodies that can bind the extracellular domain of the pore-forming complex, blocking complete formation of the pore and preventing sporozoite traversal Into the liver. See, e.g., Jimah et al., ELIFEe2016 Dec l;5:e20621. dol: 10.7554 / eUfe.20621, which is incorporated herein by reference in its entirety.

[0354] CeiTOS sequences are known (see, e.g., Uniprot accession number M1ETJ8, Q53UB7, A0A2R4QLA5, A0A2R4QU0, A0A2R4QLI5, A0A2R4QU1, A0A2R4QU4, M1ETJ8, Q53UB8, Q8I5P1, each of which is incorporated herein by reference in its entirety). An exemplary CeiTOS amino add sequence is provided in Table 2.

[0355] SPECT1 and SPECT2 (the latter also sometimes referred to as perforin-like protein 1 (PLP1)) are siyiificant Plasmodium proteins that may play a role in cell traversal. See Yang et al., Cell Rep. 2017 Mar 28;18(13):3105-3116. doi: 10.1016 / j.celrep.2017.03.017, which is incorporated herein by reference in its entirety. Targeted disruption of P. falciparum SPECT1 or SPECT2 has been shown to reduce infectivity of sporozoites in liverstage development in humanized mice. However, mechanisms of cell traversal of these two proteins are yet to be defined in P. falciparum. See Yang et al.

[0356] SPECT1 and SPECT2 are considered attractive pre-erythrocytic immune targets due to the key role they are thought to play in the crossing of the malaria parasite across the dermis and the liver sinusoidal wall, prior toinvasion of hepatocytes. Recombinant P. falciparum SPECT2 has been shown to cause lysis of red blood cells in a Ca2-* -dependent manner, as has the MACPF / CDC domain of ASPECT2. ASPECT2 has also been implicated in the Ca2+ -dependent egress of P. falciparum merozoites from red blood cels.

[0357] SPECT1 and SPECT? sequences are known (see, e.g., UniProt accession numbers Q8IDR4 and Q9U0J9, each of which is incorporated herein by reference in its entirety), and exemplary amino add sequences for SPECT1 and SPEC!? are provided in Table 2.Exported Protein 1 (EXP 1

[0358] Exported protein 1 (EXP1) is a single pass transmembrane protein with an N-terminal signal peptide expressed during intraerythrocytlc stage and liver stage (see, e.g., Spielmann et al., Int J Med Microbiol. 2012 Oct;302(4-5): 179-86, which is Incorporated herein by reference In its entirety). EXP1 was shown to Initially localize to dense granules in merozoites and then be transported to parasltophorous vacuolar membrane (PVM) after invasion (see, e.g., Iriko et al., Parasitol Int. 2018 Oct;67(5):637-639, which is incorporated herein by reference in its entirety). Once localized to the PVM, EXP1 forms homo-oligomers with a N-terminus that is exposed to the parasltophorous vacuolar lumen and a C-terminus that is exposed to the red blood cell cytosol (see, e.g., Mesén- Ramrez et al., PLoS Biol. 2019 Sep 30;17(9):e3000473, which is Incorporated herein by reference in Its entirety).

[0359] EXP1 has been demonstrated to possess glutathione S-transferase (GST) activity that may protect Plasmodium from oxidative damage (see, e.g., Mesén-Ramirez et al., PLoS Biol 17(9) 2019 Sep 30;17(9):e3000473, which is incorporated herein by reference in its entirety). Recently, it was demonstrated that EXP1 is important for Plasmodium survival by maintaining correct localization of EXP2, a nutrient-permeable channel in the PVM (see, e.g., Mesen-Rami'rez et al., PLoS Biol. 2019 Sep 30;17(9):e3000473, which is Incorporated herein by reference in Its entirety).

[0360] P. falciparum EXP1 polypeptide sequences are known (see, e.g., UniProt accession number Q8IIF0,W7JTD3, Q25840, Q548U2, Q5VKK2, Q5VKK5, Q5WRH8, Q6V9G4, Q6V9G6, Q6V9G9, Q6V9H1, Q6V9H2, Q9U590, P04923, P04926, each of which is Incorporated herein by reference in its entirety). An exemplary EXP1 amino add sequence Is provided in Table 2.Unregulated In Infective Sporozoites Gene 3 (UIS3)

[0361] Upregulated in infective sporozoites gene 3 (UIS3) is a membrane-bouxi protein localized to sporozoite parasltophorous vacuolar membrane (PVM) in infected hepatocytes. UIS3 was shown to interact with liver fatty addbinding protein (L-FABP) and be involved in fatty acid and / or lipid import during phases of Plasmodium growth (see, e.g., Sharma et al., J Biol Chem. 2008 Aug 29; 283(35): 24077-24088; Mikolajczak et al., Int J Parasitol. 2007 Apr;37(5):483-9, each of which is incorporated herein by reference in its entirety).

[0362] After sporozoite invasion of host liver cells, there Is synthesis of vital Plasmodium structural features (e.g., parasltophorous vacuolar membrane). During hepatocytic stages, the Plasmodium relies on host fatty adds for rapid synthesis of its membranes (see, e.g., Sharma et al., J Biol Chem. 2008 Aug 29; 283(35): 24077-24088, which is incorporated herein by reference in its entirety). UIS3 insertion in the PVM provides Plasmodium a method to import essential fatty adds and / or lipids during rapid sporozoites growth phases (see, e.g., Sharma et al., J Biol Chem. 2008 Aug 29; 283(35): 24077-24088, which is incorporated herein by reference in its entirety).

[0363] Immunization with UIS3-defident Piasmodum berghei sporozoites protected against malaria in rodent malaria model (see, e.g., Mueller et al., Nature. 2005 Jan 13;433(7022): 164-7, which is incorporated herein by reference in its entirety). UIS3-defident Plasmodium berghei can start the transformation process in the liver;however, they show severe defects during transformation into trophozoites (see, e.g., Mueller et al., Nature. 2005 Jan 13;433(7022): 164-7, which is incorporated herein by reference in its entirety). UIS3-deficient Plasmodium berghei are also unable to develop into mature liver schizonts and therefore abort malaria infection within the liver itself (see, e.g., Mueller et al., Nature. 2005 Jan 13;433(7022): 164-7, which is incorporated herein by reference in its entirety). Further, it was previously demonstrated that UIS3 derived from Plasmodium berghei and UIS3 derived from Plasmodium faldparum exhibited a low (i.e. 34%) amino acid sequence identity (see, e.g., Mueller et al., Nature. 2005 Jan 13;433(7022): 164-7, which is incorporated herein by reference in its entirety).

[0364] Plasmodium UIS3 sequences are known (see, e.g., UniProt accession number A0A509ARS3, A0A1C6YLP3, Q8IEU1, A0A384KU1, A0A1G4H423, A0A077YB01, Q9NFU4, each of which is Incorporated herein by reference In Its entirety). An exemplary U1S3 amino acid sequence Is provided In Table 2.Early Transcribed Membrane Protein 10.3 (ETRAMP10.3) and Unregulated in Infective S es Gene 4 (UIS4)

[0365] Upregulated in infective sporozoites gene 4 (UIS4) contains a single transmembrane domain and localizes to secretory organelles of sporozoites and to the parasitophorous vacuole membrane (PVM) of liver stages. UIS4 is not expressed In blood stages or early sporozoites that are produced in oocysts (see, e.g., Mackellar et al., Eukaryot Cell. 2010 May; 9(5): 784-794, which is incorporated herein by reference in Its entirety).

[0366] Deletion of UIS4 gene is associated with arrest of early liver stage development (see, e.g., Vaughan and Kappe, Cold Spring Harb Perspect Med. 2017 Jun l;7(6):a025486, which Is Incorporated herein by reference in its entirety). Recently, UIS4 was demonstrated to be Involved in Plasmodium berghei survival by eluding host actin structures deployed as part of host cytosolic defense (see, e.g., Sana et al., (Science. 2022 Apr 22;25(5): 104281. doi: 10.1016 / j.isci.2022.104281. eCollection 2022 May 20, which Is Incorporated herein by reference In Its entirety). P. falciparum has an ortholog to UIS4 named ETRAMP10.3 which is not able serve as a functional compliment to P. yoeliiUIS4, Indicating It likely serves a different function In P. falciparum's lfie cycle (see Mackdlar et al., Eukaryot Cell 9:784-94 (2010), which is incorporated herein by reference In its entirety).

[0367] Plasmodium faldparum early transcribed membrane protein 10.3 (ETRAMP10.3) Is an approximately 10 kDa protein and member of the early transcribed membrane proteins multigene family, a family which is conserved across Plasmodium species and includes proteins located In the parasitophorous vacuole. Several ETRAMP proteins are specific to P. faldparum and not found In Plasmodium species that infect other organisms. ETRAMP10.3 is one example, which is expressed in both liver and blood stage P. faldparum parasites. ETRAMP10.3 transcription has been found to peak during the transition from ring to trophozoite stages of P. faldparum blood stage infection in a human host ETRAMP10.3 localizes to the parasitophorous vacuole and is exported to a host erythrocyte during blood stage infection. Although ETRAMP10.3 is sometimes referred to as Upregulated in Infectious Sporozoites gene 4 (UIS4), ETRAMP10.3 is understood to be an ortholog of UIS4 on the basis of synteny and structural similarity.However, ETRAMP10.3 is not a functional ortholog of UIS4 and may play a different biological role. Although the biological function of ETRAMP10.3 has not yet been completely resolved, localization to vesicular structures in the host erythrocyte suggests a role in host-parasite interaction or in remodeling of infected erythrocyte. ETRAMP10.3 appears to play a key role in the Plasmodium life cycle. When ETRAMP10.3 is deleted, the deletion can lead to the disruption of liver-stage development in mice and asexual blood stage progression.

[0368] Although the terms “UIS4" and "ETRAMP10.3” are in the literature sometimes used to refer to different proteins, in context of the present disclosure, the terms "UIS4* and "ETRAMP10.3" interchangeably to refer to ETRAMP10.3.

[0369] Plasmodium UIS4 sequences are known (see, e.g., UniProt accession number Q8DM9, which is incorporated herein by reference in its entirety). An exemplary UIS4 amino add sequence is provided in Table 2. Liver Specific Protein 1 fUSP-1)

[0370] Liver specific protein 1 (LISP-1) is expressed during Plasmodium development in hepatocytes and localized to the parasitophorous vacuolar membrane (PVM) (see, e.g., Ishino et al., Cell Microbiol. 2009 Sep; 11(9): 1329-1339, which is incorporated herein by reference in its entirety). LISP-1 was shown to be expressed at high levels during late liver stages development and to be involved in PVM breakdown and subsequent merozoite release (see, e.g., Ishino et al., Cell Microbiol. 2009 Sep; 11(9): 1329-1339, which is incorporated herein by reference in its entirety).

[0371] Intracellular Plasmodium deficient In LISP-1 develop into hepatic merozoites and display normal infectivity to erythrocytes (see, e.g., Ishino et al., Cell Microbiol. 2009 Sep; 11(9): 1329-1339, which is incorporated herein by reference in its entirety). However, USPl-defident liver-stage Plasmodium do not rupture PVM and remain trapped inside hepatocytes (see, e.g., Ishino et al., Cell Microbiol. 2009 Sep; 11(9): 1329-1339, which is incorporated hereto by reference in its entirety).

[0372] Plasmodium LISP-1 sequences are known (see, e.g., UniProt accession number A0A210C2X6, Q8ILR5, each of which is incorporated herein by reference in its entirety). An exemplary LISP-1 amino add sequence is provided In Table 2.Liver Specific Protein 2 fLISP-2)

[0373] Liver spedfic protein 2 (LISP-2) contains a modified 6-cys domain and is expressed during Plasmodium development in hepatocytes (see, e.g., Orito et al., Mol Microbiol. 2013 Jan;87(l):66-79, which is incorporated herein by reference In Its entirety). LISP-2 was shown to be expressed by liver stages Plasmodium, exported to hepatocytes, and be distributed throughout the host cell, including the nucleus (see, e.g., Orito et al., Mol Microbiol. 2013 Jan;87(l): 66-79, which is incorporated herein by reference In Its entirety).

[0374] Intracellular Plasmodium deficient in LISP2 do not mature effectively during merozoites development (see, e.g., Orito et al., Mol Microbiol. 2013 Jan;87(l):66-79, which is incorporated herein by reference In its entirety).

[0375] Plasmodium LISP-2 sequences are known (see, e.g., UniProt accession number A0A2I0BZR4, Q8I1X6, Q9U0D4, each of which is Incorporated hereto by reference in its entirety). An exemplary LISP-2 amino add sequence is provided in Table 2.Thrombosoondin-Related Adhesion Protein fTRAP)

[0376] Thrombospondin-related adhesion protein (TRAP) contains an N-terminal domain that is commonly referred to as von Willebrand factor A domain, although it is most similar to an integrin I domain because it contains a metal Ion-dependent adhesion site (MIDAS) with a bound Mg2tIon that Is required for sporozoite motility In vitro and infection in vivo (see, e.g., Lu et al., PLoS One. 2020; 15(1): e0216260, which is incorporated herein by reference in its entirety). The I domain is inserted in an extensible p-ribbon and followed by a thrombospondin repeat (TSR) domain, a proline-rich segment at the C-terminus, a single-pass transmembrane domain, and a cytoplasmic domain (see, e.g., Lu et al., PLoS One. 2020; 15(1): e0216260, which is incorporated herein by reference in its entirety). Sequence analysis of the proline-rich segment revealed the presence of SH3-domain binding PxxP motifs in PlasmodiumTRAPs (Akhouri et al., Malar J. 2008 Apr 22;7:63. doi: 10.1186 / 1475-2875-7-63, which is incorporated herein by reference in its entirety).

[0377] TRAP is stored in the mkronemes and becomes surface exposed at the sporozoite anterior tip when parasite comes in contact with host cells (Akhouri et al., Malar J. 2008 Apr 22;7:63. doi: 10.1186 / 1475-2875-7-63, which is incorporated herein by reference in its entirety). TRAP also plays an important role in liver cell invasion of sporozoites by helping sporozoites in gliding motility and in recognition of host receptors on the mosquito salivary gland and hepatocytes (Akhouri et al., Malar J. 2008 Apr 22;7:63. doi: 10.1186 / 1475-2875-7-63, which is incorporated hereto by reference in its entirety).

[0378] PlasmodiumTRAP sequences are known (see, e.g., UniProt accession numbers A0A5Q2EXK8, A0A5Q2EZD7, A0A5Q2F1F6, A0A5Q2F2B8, A0A5Q2F2H6, A0A5Q2F4G9, 076110, P16893, Q01507, Q26020, Q76NM2, W8VNB6, each of which is Incorporated herein by reference in its entirety), and an exemplary TRAP amino add sequence Is provided In Table 2.Liver-Staoe-Assodated Protein-1 (LSAP-1)

[0379] Liver-stage-associated protein (LSAP-1) has been shown to be found mainly at the periphery of the Intracellular hepatic parasite throughout its development, but not in blood stage parasites and possibly in minor quantities In salivary gland sporozoites (see, e.g., Siau et al., PLoS Pathog. 2008 Aug 8;4(8):el000121, which Is Incorporated herein by reference In Its entirety). LSAP-1 is among the most abundant transcripts In the salivary gland transcriptome but has not been detected in proteomlc surveys of sporozoites. Rather, expression has only been detected only In liver stages (see, e.g., Slau et al., PLoS Pathog. 2008 Aug 8;4(8):el000121, which is Incorporated herein by reference In its entirety).

[0380] Plasmodium LSAP-1 sequences are known (see, e.g., UniProt accession number Q8I632, W7JR53, each of which Is incorporated herein by reference in Its entirety). An exemplary LSAP-1 amino add sequence is provided In Table 2.Liver-Stage-! "Delated Protein-2 fLSAP-2)

[0381] Like LSAP-1, LSAP-2 Is also among the most abundant transcripts In the salivary gland transcriptome but has not been detected in proteomlc surveys of sporozoites. LSAP-2 has shown some efficacy as a vaccine when combined with other antigens. See, e.g., Halbroth et al., Infect Immun. 2020 Jan 22;88(2):e00573-19. doi: 10.1128 / IAI.00573-19. Print 2020 Jan 22, which Is incorporated herein by reference In its entirety.

[0382] Plasmodium LSAP-2 sequences are known (see, e.g., UniProt accession number Q8I632, W7JR53, each of which is incorporated herein by reference in its entirety). An exemplary LSAP-2 amino add sequence is provided in Table 2.Liver-Staae Antigen 1 (LSA-1)

[0383] Liver-Stage Antigen 1 (LSA-1) is expressed after Plasmodium have invaded hepatocytes and antigen accumulates in the parasitophorous vacuole (see, e.g., Tucker, K. et al., 2016, 'Pre-Erythrocytic Vaodne Candidates in Malaria', in A. J. Rodriguez-Morales (ed.), Current Topics in Malaria, IntechOpen, London. 10.5772 / 65592, each of which is incorporated herein by reference in its entirety). The function of LSA-1 remains currently not known (see, e.g., Tucker, K. et al., 2016, 'Pre-Erythrocytic Vacdne Candidates in Malaria', in A. J. Rodriguez-Morales (ed.), Cun-ent Topics in Malaria, IntechOpen, London. 10.5772 / 65592, which is incorporated herein by reference in its entirety).

[0384] LSA-1 is a 230 kDa preerythrocytic stage protein containing a large central region consisting of over eighty 17 amino add residue repeat units flanked by highly conserved C- and N-termlnal regions (Richie, T.L. and Parekh, F.K. (2009) Malaria, which is incorporated herein by reference in its entirety). In Vaccines for Biodefense andEmerging and Neglected Diseases (Barrett, A.D.T. and Stanberry L.R., eds), pp. 1309-1364, Elsevier, which is incorporated herein by reference in its entirety). LSA1 is expressed only by liver stage Plasmodium and not by sporozoites (Richie, T.L. and Parekh, F.K. (2009) Malaria, which is incorporated herein by reference in its entirety). In Vaccines for Biodefense and Emerging and Neglected Diseases (Barrett, A.D.T. and Stanberry L.R., eds), pp. 1309- 1364, Elsevier, which is incorporated herein by reference in its entirety). The repeat region results in significant variation of the protein between strains of Plasmodium falciparum (see, e.g., Tucker, K. et al., 2016, 'Pre-Erythrocytic Vaccine Candidates in Malaria', in A. J. Rodriguez-Morales (ed.), Current Topics in Malaria, IntechOpen, London. 10.5772 / 65592, which is incorporated herein by reference in its entirety).

[0385] Plasmodium LSA-1 sequences are known (see, e.g., UniProt accession number Q25886, Q25887, Q25893, Q26028, Q9GTX5, 096125, each of which Is Incorporated herein by reference In Its entirety). An exemplary LSA-1 amino acid sequence is provided in Table 2.Liver stage antigen 3 (LSA-3)

[0386] Liver stage antigen 3 (LSA-3) Is a 200-kDa protein that Is composed of three nonrepeating regions (NR- A, NR-B, and NR-C) flanking two short repeat regions and one long repeat region (see, e.g., Tucker, K. et al., 2016, 'Pre-Erythrocytic Vaccine Candidates in Malaria', in A. J. Rodriguez-Morales (ed.), which Is incorporated herein by reference in its entirety), Current Topics in Malaria, IntechOpen, London. 10.5772 / 65592, which is incorporated herein by reference in its entirety). The nonrepeat regions are well conserved across geographically diverse strains of Plasmodium faidparum (see, e.g., Tucker, K. et al., 2016, 'Pre-Erythrocytic Vaccine Candidates in Malaria', in A. J. Rodriguez-Morales (ed.), Current Topics In Malaria, IntechOpen, London. 10.5772 / 65592, which is Incorporated herein by reference in Its entirety). The most significant variation Is In the repeating regions due to organization and number of repeating subunits rather than composition of the repeating regions (see, e.g., Tucker, K. et al., 2016, 'Pre-Erythrocytic Vaccine Candidates In Malaria', in A. J. Rodriguez-Morales (ed.), Current Topics in Malaria, IntechOpen, London. 10.5772 / 65592, which is Incorporated herein by reference In its entirety).

[0387] Recently, in vitro data has shown that antibodies against LSA-3 (in particular, the C-termlnal portion of LSA-3) may provide some protection (see, e.g., Morita et al, Sci Rep. 2017 Apr 5;7:46086. doi: 10.1038 / srep46086, which is incorporated herein by reference in Its entirety).

[0388] Plasmodium LSA-3 sequences are known (see, e.g., UniProt accession number C7DU21, C7DU22, C7DU23, C7DU24, C7DU25, C7DU26, C7DU27, C7DU28, C7DU29, C7DU32, C7DU33, C7DU34, C7DU36, C7DU37, C7DU38, C7DU39, C7DU40, Q8I042, Q8I0A5, Q8I0D0, Q8IFR1, Q8IFR2, Q8IFR3, Q8IFR4, Q8IFR5, Q8IFR6, Q8IFR7, Q8IFR8, Q8IFR9, Q8IFS0, Q8IFS1, Q8IFS2, Q8IFS3, Q8IFS4, Q8IFS5, Q8IFS6, Q8IFS7, Q8IFS8, Q8IFS9, Q8IFT0, Q8IFT1, Q8IFT2, Q8IFT3, Q8IFT4, Q9U0N9, Q9U0P0, A0A2I0BVD6, A0PFM9, 096275, each of which is incorporated herein by reference In its entirety). An exemplary LSA-3 amino acid sequence is provided In Table 2.Glutamic Add-Rich Protein

[0389] Glutamic add-rich protein (GARP) is a 80kDA protein which derives its name from its glutamic rich amino add sequence which comprises 24% of all its residues. GARP Is predominantly expressed in ring stages and trophozoites and has been shown to be a non-essential gene in cell culture but highly immunogenic in animal models. Although GARP is non-essential in cell culture, its localization to the periphery of infected erythrocytes may indicate a role in the sequestration of infected erythrocytes. CARP'S involvement in sequestration has been proposed to occur by way of binding with an chloride / bicarbonate anion exchanger. Antibodies against GARP have been proposed to serve as signatures of protection against severe malaria and have shown efficacy in experimental trialsSEQ ID Protein Sequence (Amino Add) NO:7 CSP
